Luigi Auriemma has discovered a vulnerability in Trend Micro OfficeScan, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in PolicyServer.exe and can be exploited to cause the service to terminate via a HTTP request to the cgiABLogon.exe CGI module with a specially crafted, overly long "pwd" parameter. The service then restarts after a few seconds.
Successful exploitation requires that the Trend Micro Policy Server for Cisco NAC is installed.
Other errors e.g. NULL-pointer dereference errors in certain CGI modules when handling HTTP requests containing certain characters or with invalid "Content-Length" headers have also been reported.
The vulnerability is confirmed in version 8.0 with Patch 2 build 1189. Other versions may also be affected.
